TYPE 2: Field Bricks CALCULATION

VOLUME = 2.14 m3

size of Brick used in field= 230x114x76 = 0.00199272 m3

Nominal Size after mortar addition = 230x124x86 = 0.00245 m3

Here we does not add mortar along length of brick because generally nowadays 9″ inches wall is considered and outer face is calculated as plaster area. You can add mortar if width of wall is more than 1 brick.

Required Number of Bricks = 2.14/0.00245 = 873 Bricks

So Actual Number of Bricks for 1 Cubic metre in field = 873/2.14 = 408 Bricks

Actual number varies from meson to meson because some one use less mortar and some one use more mortar. so it is mainly 390 to 430.
